Is this a obtuse angle? Explain

2 answers:

8 0

An obtuse angle is an angle that is more than 90 degrees (a right angle). So Anywhere from 91 degrees to 179 degrees is an obtuse angle. 180 degrees would be a straight line. An acute angle would be anywhere from 1 degree to 89 degrees.

An easy way to remember this is to use your index finger and your thumb. When they are close together you can think of a cute little bug, such as the acute angle. When your fingers make an L then you an think of it being a right angle ( Right being the opposite of left). Lastly you an think of your fingers being longer than a right angle as an obtuse elephant.

This helped me a whole lot when i was in 6th and 7th grade and i hope it helps you too.

Answer:

The change in motion is being decreased. I know this because the graph shows that every 0.5 seconds it is slightly being increased by distance causing there to be more drag resulting in there being a increase in time. the acceleration is negative.

a water balloon is tossed into the air with an upward velocity of 25 ft/s its height h(t) in ft after t seconds is given by the

Montano1993 [528]

When the height is 0 that is when it hits the ground
solve
0=-16t²+25x+3
cant factor so use quadratic formula

for
0=ax²+bx+c
$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$

so for
0=-16t²+25t+3
a=-16
b=25
c=3
so

$x=\frac{-25+/-\sqrt{25^2-4(-16)(3)}}{2(-16)}$
$x=\frac{-25+/-\frac{625+192}}{-32}$
$x=\frac{-25+/-\frac{817}}{-32}$
it has to be a positive time

so it will hit the ground after $\frac{25+\sqrt{817}}{32}$ seconds
